The crank thread got me thinking of all the other settings that are compared to a road set up and reality. I have always believed theory and books are nice to know things but nothing replace's old actual practice. So how do the rest of these things stack up. Seat height, is yours 10mm lower than your road set up? Stem length 10mm shorter? Handle bars next size wider? Handle bar height 10mm taller? It would be interesting to see how the reference works compare to actual practice, and give me a starting point for my set up.

I understand that, i'm just wondering where people end as compared to their road bike set up.`

52cm cross frame center to top, I have two cross bikes
52cm road frame center to top, the frame is a cm or two small in standover but fine in top tube length.
54cm + 54.5cm top tube on the cross/ 55cm on the road.
120mm stem on the 54cm top tube cross bike
110mm stem ont he 54.5cm top tube cross
110mm stem on the road bike (I need a longer stem or layback
The stem on the 54cm top tube cross bike has a quill stem raised up to the max height, no rise.
The stem on the 54.5cm top tube cross has 1" worth of spacers, no rise.
Stem on the road bike is a salsa with 5 degree rise.
Cranks on both cyclocross bikes 175mm
Cranks on the road bike are 170mm
I use straight posts on all bikes, but I am looking for a layback for the road frame.
Regarding seat post extension, a minimal 5mm? difference

I am 5'7 / 5'8? with northwaves. I perfer a 78cm standover height on the cyclcocross frames, and a 79-80cm on road I suppose. 54-55cm top tubes work.

hope this helps.

for me seat height is maybe 5mm lower at the most, my stem is 10 mm shorter (not even sure this does much for me, I might go 10mm longer next year) and nothing else is different, same bars, same negative rise stem etc.

Once I finally buy the frame, here are the specs I will be using compared to my road bike:

Stem: 120mm (130mm on road bike)
Top Tube: 57cm c-c (58cm c-c on road bike)
Seat Tube: 59cm c-t (59cm c-c on road bike)
Stem height: Not certain, but probably at least 1cm higher than on road bike. I will be using the Cinelli Solido stem, and I'm going to test using the 110 degree rise on the CX bike.
Seat height: 79cm center of B/B to top of seat (currently 80cm on the road bike) This adjustment will be played around with.
Bar width: 44cm Cinelli (same as on road bike)

Thanks every one. I've been thinking about the bars and why references would say a wider bar. One thing Ive thought of is it seems, this is comming from observation mind you as I haven't gotten out yet, alot of time is spent on the top of the bar. Not the hoods but the actual cross bar, so a little wider bar would give a wider more controlable grip for this position. Any comments from the ones that are actually riding? ( I asy that because as I say I'm not)

Good specs for a cross bike - it's almost identical to how I have my cross bike set up compared to my road bike. Let me know when you get the frame and bring it on by and we can build it up if you want.

I'm riding fairly long both days this weekend...want to join me for Sat and/or Sun?
